The energy released from ATP ADP + is just about enough for most biological reactions. D. Function of ATP 1. Chemical work: ATP supplies energy to synthesize macromolecules that make up the cell. 2. Transport work: ATP supplies energy needed to pump substances across the plasma membrane. 3. Mechanical work: ATP supplies energy to move muscles, cilia and flagella, chromosomes, etc.
